I want to calculate the difference between two dates in days such that for hours from 1-23 we consider it as a day. for example: Date1 = '2021-06-15 01:52:00.926+00' Date2 = '2021-06-15 02:52:00.926+00' Here, Date1-Date2 = 1hour. I want to take ceil of it to be 24hrs i.e 1 day. I tried (Date2::DATE - Date1::DATE) but it gives 0. There can be two scenarios: If difference between days is 35hrs it should return 3(i.e 3 days). If the difference between dates is 5hrs it should return 1(i.e 1 day).

I have a dynamic grid which looks something like this

I am using this template in my overleaf Report:

If link is not accesible here is the code:

We would like SwaggerUI, which is being generated by Swashbuckle, to show all controllers and methods when debugging as well as on our test environment, but hide some on integration and production environments. Note that the hidden controllers/methods will be functional in all scenarios but won't be documented in SwaggerUI.

To do this I've applied the principal described here.

Which results in following code:

Hi I am developing a runtime using Substrate-FRAME and I would like to know how can I write a system test for my runtime?

The main purpose of writing a system test is to ensure that the final build is fulfilling all of the required specifications and also to ensure nothing is compromised on a runtime upgrade. The idea for me is something similar to point no. 2 mentioned in this thread.

Any documentation regarding this type of tests would be greatly helpful.

Update:

I ended up using py-substrate-interface to make test scenarios. Now I can automatically deploy nodes to form a network (thanks to Python) and run my custom system test scenarios. Very useful tool for developing runtimes in Substrate.

I have tried the PUT request by XMLHttpRequest. There is a browser-side limitation that doesn't allow me to upload files larger than 2GB. Then I have tried the POST request from an HTML form that doesn't require Javascript side preprocessing. It has 5GB upload size limitation in a single operation.

AWS recommended multipart upload in larger upload scenarios. That requires files to chunk down then upload into pieces. How to do it right from the browser, when the file size is greater than 10GB.

I am new to embedded C, and I recently watched some videos about volatile qualifier. They all mention about the same things. The scenarios for the use of a volatile qualifier :

1. when reading or writing a variable in ISR (interrupt service routine)
2. RTOS application or multi thread (which is not my case)
3. memory mapped IO (which is also not my case)

My question is that my code does not stuck in the whiletest();function below when my UART receives data and then triggers the void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) interrupt function

I am trying to make a function that should return NA of the same class as function's input. So, for example, myNA('abc') returns NA_character_, myNA(123L) - NA_integer_, etc.
I tried something like this:

Why the following command is slow (5 mins)?
